A step to control judiciary?

Impeachment of judges of Supreme Court has become a new issue of debate. The government recently took initiative to restore the original constitutional provision to impeach judges of the Supreme Court, claiming that it is one of the basic features of Westminster type democracy which we follow. The reasoning provided by the government is correct but problem lies elsewhere. Do we really follow Westminster type democracy?
Our constitution states that “all power belongs to the people” (art.7), but can people exercise their power at all? Parliament is said to be the centre of all national issues but the reality is the opposite. Members of Parliament as the representatives of people legislate law, but they hardly discuss the issues of public interest in parliament. Each and every decision comes from one person, the Prime Minister. People wonder if impeachment of judges is a new step to control the judiciary.
